Power from the diesel engine (7) is sent from
the engine flywheel (12) through the torque converter
(6). The output shaft of the torque converter sends the
power through upper drive shaft (5) to the input shaft of
transmission (2) has six clutches which are hydraulically
engaged. Two clutches turn and the other four clutches
are stationary. Four planet systems are used in
combination with the six clutches to give four speeds
forward and two speeds reverse. The direction and
speeds are changed manually.
The output shaft of the planetary transmission
sends the power to the output transfer gears (1). From
the output transfer gears (1), power goes through the
lower drive shaft (8) to the pinion shaft and bevel gear
(9). The pinion shaft and bevel gear send the power
through the differential (10). The differential sends the
power to the final drives and wheels (11).
Splines are used as connections between the
axles and the sun gears of the final drives. When the
sun gears turn, the planet gears in the carrier move
around the inside of the stationary ring gear. This action
turns the carrier and the wheels.
